When the fort guarding the suspension bridge over the Great Rift fell into the hands of the Quagoa, the Commander-in-Chief ordered his men to seal the gates of the fortress protecting the entrance to Feo Jera. While the Quagoa were momentarily halted, it was only a matter of time before they breached the walls of the fort.

He was notified that a group of monsters were waiting outside the fortress guarding the entrance to Feo Jera above ground and were requesting entry. Learning that they were a delegation from the Sorcerer Kingdom wishing to open trade relations, and warn the dwarves of a massive Quagoa invasion. The Commander, shocked by the newcomers and the news they brought agreed to allow them entry.

He accepted the offer of military assistance to repulse the Quagoa at the fortress and bore witness to the slaughter of the demi-humans at the swords of two Death Knights summoned by Ainz. After Quagoa had fled, he agreed to take the Sorcerer King to the Regency Council.

During the initial negotiations, the Commander-in-Chief expressed his interest in acquiring undead warriors from the Sorcerer Kingdom to serve as a defensive force for the Dwarf Kingdom.

In the Regency Council's private discussion, many of the councilors were unanimous in rejecting the Sorcerer King’s proposal, due to their prejudice against the undead. The Commander-in-Chief was the sole voice of opposition in those talks; after convincing them that the Dwarf Kingdom would be destroyed without the Sorcerer King's aid, several of the councilors changed their decision and supported he proposal, except the Forgemaster who believed the were betraying their people to a monster.

After a brief physical confrontation with his colleague, the Council through majority vote agreed to request the aid from the Sorcerer Kingdom and open trade relations.

The Commander accompanied the Sorcerer King and his attendants to the fortress that guarded the suspension bridge over the Great Rift. After confirming the Quagoa retreated he saw off the party as they made their way to the city of Feo Berkana.

When the Forgemaster had disappeared along with the item entrusted to him by Ainz, the Commander was in charge on locating him, but failed to find any trace of him.

While his colleagues saw the Sorcerer King as an undead monster, he saw him as a necessary evil and possibly final hope for the dwarven race. He acknowledges the power of Ainz Ooal Gown and even his fellow councilors note that he refers Ainz as his 'majesty' rather 'monster' as a sign of proper respect.
